Abstract
The invention discloses a bonding process of flexible substrates and a frame rubber pattern thereof. The bonding process mainly for manufacturing flexible liquid crystal displays comprises steps: between a first substrate and a second substrate, firstly bonding the frame rubber pattern to a first substrate by utilizing patterns of frame rubber gaps, filling liquid crystal into the frame rubber, compressing the first and second substrates, then automatically exhausting air bubbles from the frame rubber gaps, and finally leading the compressed frame rubber to generate expansion deformation, thereby automatically sealing the frame rubber gaps. The bonding process utilizes the designed frame rubber gap patterns to exhaust air bubbles easily by the flexible liquid crystal display during bonding process in atmosphere, and enable the frame rubber gap patterns to be automatically sealed directly in the bonding process.
Description
Technical field
The present invention relates to a kind of attaching process of flexible substrate and the frame glue pattern of use thereof, particularly a kind of being suitable for fitted under the atmosphere and can be got rid of bubble and the flexible substrate attaching process of automatic involution and the frame glue pattern of use thereof.
Background technology
Liquid crystal flat panel display needs to carry out liquid crystal filling and the action of sealing in manufacturing process, the method of the general inclined to one side use of industry at present has two kinds, a kind of is the mode that the vacuum capillary sucks, and another kind is the vacuum formula liquid injection mode (ODF, One Drop Filling) of dripping.The mode that the vacuum capillary sucks is that the panel of finishing fitting is placed in the cabin body, after waiting to have vacuumized, the panel of jagged direction is placed in the liquid crystal groove, vacuum breaker in the body of cabin, owing in the panel vacuum volume is arranged, therefore can be with in the liquid crystal suction panel, to reach the purpose of liquid crystal filling, the intact panel of filling seals by carrying out frame glue again after having cleaned to the outside.Please refer to the drip patent (as shown in Figure 1) of formula liquid crystal injection mode of US6552772 vacuum is with the last lower glass substrate 11 of picture frame glue 10,12 place the sucker up and down in the cabin body 13, lower glass substrate is dripped liquid crystal 14, carries out the contraposition applying after cabin body 13 has vacuumized then and does 10 curing of frame glue again.More than the mode injected of two kinds of liquid crystal all need to vacuumize, so the process time is longer, the equipment cost height, and relatively can waste liquid crystal in the vacuum capillary suction process, need again to clean and technological action such as seal, process time is longer, and cost is higher, the inapplicable filling in the pliability LCD of these two kinds of liquid crystal filling methods with seal.Relatively, the pliability LCD is fitted cheaply operation under the atmosphere, but when atmosphere retrofilling and sealing operation, and the air bubble problem of puzzlement, and the problem of additionally sealing processing does not obtain preferable solution yet.
Summary of the invention
In view of this, technical matters to be solved by this invention is, the filling of a kind of flexible base plate under atmosphere is provided and can reaches the effect and the self-sealing manufacturing technology of degassing and steeping.
The present invention addresses the above problem, and the invention provides the attaching process of a flexible substrate, comprises: one first base material is provided; Paste a solid graphical frame glue on first base material, and graphical frame glue has at least one breach; Filling one liquid is in the first base material upper surface and graphical frame glue institute region; Pressing one second base material covers this graphical frame glue, this liquid and this first base material upper surface, graphical frame glue is extended and automatic this breach of involution behind pressurized, with coat fully this liquid around; This graphical frame glue of final curing.
The liquid of the described filling of the invention described above between first base material and second base material can be liquid crystal or plastering agent.
The described graphical frame glue of the invention described above is a solid-state glue, and mainly utilizes irradiation ultraviolet radiation light to be solidified.
The described pressing mode of the invention described above can utilize the running roller pressing also to proceed to second limit with breach by first limit of this graphical frame glue in regular turn.
Using the effect that the present invention obtained is, the present invention is at the liquid crystal of atmosphere retrofilling flexible substrate (or plastering agent), behind the attaching process of collocation pressing, can discharge unnecessary liquid crystal or plastering agent automatically, and discharge can't be avoided the bubble of meeting generation, again can be when finishing applying, automatic sealing.So but technology is low than the equipment cost of prior art, the process time is short and the atmosphere retrofilling, must not provide vacuum environment and equipment, size is unrestricted, and does not need cleaning and seal after filling is intact, for shortening widely on the process time, promote competitive edge.
